Universal Cap For Male And Female Connectors

TECHNICAL FIELD

The present disclosure generally relates to a device for disinfecting and sterilizing access ports with, e.g., male and female luer fitting, and, in particular, to disinfecting and sterilizing devices capable of accommodating multiple types of connectors.

BACKGROUND

Vascular access devices (VAD's) are commonly used therapeutic devices and include intravenous (IV) catheters. There are two general classifications of VAD's, peripheral catheters and central venous catheters. Bacteria and other microorganisms may gain entry into a patient's vascular system from access hubs and ports/valves upon connection to the VAD to deliver the fluid or pharmaceutical. Each access hub (or port/valve or connection) is associated with some risk of transmitting a catheter related bloodstream infection (CRBSI), which can be costly and potentially lethal.

In order to decrease CRBSI cases and to ensure VAD's are used and maintained correctly, standards of practice have been developed, which include disinfecting and cleaning procedures.

Disinfection caps have been added to the Society for Healthcare Epidemiology of America (SHEA) guidelines and early indications are that caps will also be incorporated into the 2016 Infusion Nurses Standards (INS) guidelines.

In developed markets, when utilizing an IV catheter, a needleless connector will typically be used to close off the system and then subsequently accessed to administer medication or other necessary fluids via the catheter to the patient. INS Standards of Practice recommend the use of a needleless connector and state that it should be “consistently and thoroughly disinfected using alcohol, tincture of iodine or chlorhexidine gluconate/alcohol combination prior to each access.” The disinfection of the needleless connector is ultimately intended to aid in the reduction of bacteria that could be living on the surface and possibly lead to a variety of catheter related complications including CRBSI. Nurses will typically utilize a 70% isopropyl alcohol (IPA) pad to complete this disinfection task by doing what is known as “scrubbing the hub.” However, compliance to this practice is typically very low. In addition to a lack of compliance to “scrubbing the hub”, it has also been noted through clinician interviews that there is often a variation in scrub time, dry time and the number of times the needleless connector is scrubbed.

Throughout the sequence of procedures associated with the transmission of a microorganism that can cause a CRBSI, there are many risks of contact or contamination. Contamination can occur during drug mixing, attachment of a cannula, and insertion into the access hub. Because the procedure to connect to a VAD is so common and simple, the risk associated with entry into a patient's vascular system has often been overlooked. Presently, the risk to hospitals and patients is a substantial function of the diligence of the clinician performing the connection, and this diligence is largely uncontrollable.

Currently, caps for male needleless connectors, female needleless connectors, intravenous (IV), and hemodialysis lines use different designs and are, therefore, limited to the types of connectors to which the cap can be attached. Thus, prior disinfecting caps were designed to fit one type of connector only, and were specific to one particular size and/or shape of connector. Thus, there is a need for a disinfecting device capable of accommodating multiple types of connectors to streamline the disinfecting process. There is also a need for a disinfecting device capable of continuous disinfection for multiple days.

Disinfecting caps currently on the market are capable of only disinfecting one of the three types of luer fitting, namely female luer of needle-free connectors, female luer of stopcocks, and male luer connectors on intravenous injection sites. Thus, to avoid having to use different types of disinfecting caps to clean different types of connectors, device 100 with cap 102 engages with male luer connectors and also with female luer connectors thereby allowing the user to clean different types of connectors with a single device. Upon mounting the cap 102 onto female luer connectors, the female luer connectors is inserted into the chamber 112 and screwed onto the threads of the cap. Upon mounting the cap onto a male luer connector, the male luer connector frictionally engage the interior wall 124 upon insertion into the chamber 112. Hence, the device of the present disclosure can be mounted onto both male and female luer connectors, thus fulfilling a current need in the art.

Other aspects of the present disclosure are directed to methods of disinfecting medical connectors and assemblies. In one or more embodiments, a method of disinfecting a medical connector comprises connecting the device of one or more embodiments to a medical connector, wherein connecting includes frictionally engaging the interior wall surface upon insertion into the chamber such that the medical connector contacts the absorbent material and the disinfectant or antimicrobial agent.
